The default permission can be set so that any data getting added to Wealthbox will default to the restriction applied (i.e. Only Me, Everyone, or a specific User Group).

An admin user with the manage users setting enabled can manage this setting for all users and restrict users from changing their default permissions setting. This can be managed from the users page in settings.

If it isn't restricted by and admin user, individual users can set their own default permissions from the Default Permissions page in settings.
